Host Institution :

UPMC

 

Objectives:

  • Qualify seismic methods as tools to capture temporal evolution of the subsurface water content/pressure.
  • Synthetize and propose links between porosity/fracture density, saturation/pressure states, hydrodynamic parameters and seismic properties in both consolidated and unconsolidated media.
  • Set up experiments to evaluate petrophysical relationships and relate available information content to subsurface properties.
  • Gain insights on the issues related to application of these methods in industry and challenges in the real world problems.

Tasks and methodology:

  1. Finding appropriate connections/links between hydrodynamic parameters and seismic properties.
  2. Exploiting the full wealth of active seismic signals and extracting information from temporal variations.
  3. Hydrogeophysical experiments with scaled seismic noise monitoring.
